Hi guys,
For connecting the power leads to my battery, should i just solder ring terminals to the wire then just attach the ring terminal to battery using the screw? (My battery has the screw type connector).
Cheers :)

Best to use a ring terminal -soldered onto the end of the wire for security.

I have a model using the 12V 20Ah batteries with the bolt on connectors.
It became a pain unbolting battery leads for removal.
I made up short 'Ring-to-Deans' adapter leads. Battery removal is now easy peasy without the need of a spanner and the adapters stay on the batteries.

Just don't use spade terminals. They will work their way loose, leaving your boat in the middle of the pond.

Cheers guys :)
@mrlownotes thats what i was thinking of to do, cheers! :)

An advantage of having a fairly permanent adapter like the Deans (or some other high current polarized connector) fitted is that it is much more difficult to connect a battery reversed.

But not impossible, Malcolm. Believe it or not Iain Lewis says that he had a customer who had blown up a NiMH pack by managing to connect it to the charger with reversed polarity.......through a Tamiya plug and socket! Stupidity of that magnitude requires a really determined idiot.
There's a fiver waiting for the first person to manage it with a Deans connector!

Oh dear Mr Inertia ....... your many years of experience should know better than to put down a challenge like this. One of the "which way round do resistors go" brigade will be making concerted efforts to claim your fiver as I type.
Look the horizon ........ I see smoke rising ! O0
PS. I note you too have visits planned to the medical folk ...... welcome to the club. And there's me thinking we're both sprightly youngsters. Hope all is well.

Ah - Stevie Steve... You should know me better by now. Nowhere did I say where the fiver was waiting or whose it is. 8)
I think "sprightly" is a bit wide of the mark in my case, but thanks for the kind thought. A Choline PET+MRI scan is due on Wednesday at St James' in Leeds; results the following week. They are excellent people there, and there's a pub on the way back (well - just outside Wakefield) which serves the best steak and ale pie in the world. I hope I can remember the way there!
Finally, if Tony Oliff is reading this.... ;D
(WTH has this to do with battery terminals? Sorry.)

You can find the way using Inertial navigation Dave.

I did only say "much more difficult". He who managed to insert a Tamiya connector (assuming that both ends were correctly wired) the reversed must have been a strong lad to get the round in the dee or 'tother way round. I would have expected the charger to go and let out the magic smoke first myself. Of course, to quote from Mike Hardings tale of the 14½ pound budgie, "With enough effort and unlimited Vaseline ®, it is possible to insert anything into anything else".
I have heard that, with persistence, it is possible to totally discharge and reform the plates of a lead acid battery in reverse like that, but it isn't really a useful trick or a recommended procedure.
